Answer:
a. y = 2+4.3x when x = -6
substituting value of x, we get
y=2+4.3*-6=2-25.8=23.8
b. y = (x-3)² when x = 9
substituting value of x, we get
y=(9-3)²=6²=36
c. y=x-2 when x = 3.5
substituting value of x, we get
y=3.5-2=1.2
d. y=5x-4 when x = - 2
substituting value of x, we get
y=5*-2-4=-10-4=-14
